The ecological dynamics of trumpet improvisation

The nature of music improvisation continues to provide an interesting showcase of the multifaceted and skilful ways we engage with and act within our environments. Improvising musicians are somehow able to generate musical material in real time that adaptively navigates musical situations. In this article I explore the broader aspects of improvised activity-such as our bodily interactions with the instrument and environment-as they relate to improvised music-making. I do so by drawing upon principles from the embodied cognitive sciences, namely ecological and dynamical systems approaches. Firstly, I introduce the concept of affordances to illustrate the bidirectional relationship between improvisor and environment. I then take a dynamical view, exploring the ways that a trumpet player coordinates their body with their instrument and engages with trumpet affordances in order to navigate musical situations. I continue this dynamical view, taking the improviser to be an adaptive system whose behaviours are self-organised responses to a set of constraints. To conclude, I situate my research within the wider 4E approach. I advocate that 'E' approaches, which take seriously the role of the body-instrument-environment relationship, provide an insightful perspective on the nature of improvisation.
